After about 6 months of driving my 2012 STI in it's stock form I finally flashed a cobb stage 1 map this weekend (91 -stock air filter, stage 1). After flashing I immediately went out for 2 quick datalogs in 4th gear, going from ~3000rm to 6000rpm. Everything looks good as far as I can determine, however on my first log I noticed my DAM decreased from 1 to .88 @5400rpm. What's puzzling me is ther both of my logs show that there was no feeback knock and very little fine learning knock (.29 in a few area's - nowhere near where the DAM decrease occurred). About 1.5 driving hours later my DAM is sitting at .94
Does anyone know why the DAM would suddenly decrease when there is no knock detected? I read up on the DAM information on Cobb's website, but it didn't seem to provide any answers. I can post the datalogs if it helps.
thanks in advance
